The only reason I didn't break this down by namespace was because they queries would have taken an order of magnitude longer to join the revision and page tables. The query I used didn't even need to read the revision or archive tables. It only read an index on those tables. That made it go pretty fast. :) I'd be interested in taking another pass if you guys don't mind dealing with a heavier server load.
